One of these features is wireless charging, which makes its way to the iPhone for the first time. In years past, Apple's Phil Schiller has said that doesn't really solve the problem, so whatever wireless charging technology Apple offers is likely to be slightly different and perhaps more user friendly.
Without confirming that's what the front-facing 3D sensor is for, my source says Apple has been struggling to get the sensor to work reliably.
The analysts said problems with finger print and 3-D sensors were to blame for the delay. A new design and a bigger OLED display are believed to be accompanied by new features like wireless charging, facial recognition, better water-resistance, and more. The issue this time is with the scarcity of OLED manufacturing.
In light of the possible Touch ID issues, another feature came into the spotlight: 3D scanning.
Temporarily depriving the Apple iPhone 8 another function. Analysts believe Apple will either delay shipments, which would presumably affect fourth-quarter financial results, or deliver the phones without the fingerprint sensor, which could hurt company unit sales and overall sales mix. Samsung is the only company that can meet Apple's volume requirements, but a recent report said that only three to four million screens could be shipped in time for launch.
There's still some time for Apple to flawless the technology, and the fact that Qualcomm and Vivo have recently launched similar tech (though it's not yet available in a phone) is promising. RBC, Cowen, KGI Securities and other firms have also suggested that the iPhone 8 could ship a little later than less technically demanding iPhone 7S models that (like the iPhone 7 and 7-Plus) are expected to sport LCD displays rather than OLEDs.
In the past few years, Apple has released two iPhones - a 4.7-inch iPhone and a 5.5-inch iPhone.
The company has precedent for this: the iPhone 7 Plus Portrait Mode, a headline feature from last year's smartphone launch, used the dual lens camera to blur the background and give photos a DSLR-like style. The report suggests that these are software issues and employees at the company are working around the clock to fix it.
Perhaps the biggest unknown surrounding the new devices at this point are when consumers will actually be able to get their hands on them.
The upcoming iPhone has been rumored to be seeking to achieve great ambitions.
